Abstract
The invention provides a weeding composition containing trifluralin, acetochlor and thifensulfuron-methyl, wherein the active ingredients comprise trifluralin, acetochlor and thifensulfuron-methyl, and the mass ratio of the trifluralin, the acetochlor and the thifensulfuron-methyl is 10-30:20-40: 0.5-2. The weeding composition can be used for preventing and removing annual weeds in crop fields and has obvious synergistic effect.
Description
Technical Field
The invention belongs to the field of herbicides, and particularly relates to a herbicidal composition containing trifluralin, acetochlor and thifensulfuron methyl and application thereof.
Background
Trifluralin is a selective aniline pre-emergence soil treatment agent, is mainly absorbed by coleoptile and hypocotyl of weeds, influences the generation and transmission of hormones, and inhibits cell division to kill the weeds. Trifluralin is not effective on emerged weeds, and can be killed only by absorbing the pesticide in the unearthing process after the weed seeds germinate. The trifluralin can effectively prevent and kill annual gramineous weeds and part of broadleaf weeds with small-grain seeds, and has longer lasting period.
Acetochlor belongs to amide herbicides, and inhibits the growth of cells by blocking protein synthesis, namely, acetochlor enters a plant body to inhibit the synthesis of protease, so that sprouts and radicles stop growing. The grassy weeds show leaf curling and shrinking, and the others also shrink, so that the whole plants die. The broadleaf weed leaves shrink and turn yellow, and the whole plants die.
Thifensulfuron methyl belongs to sulfonylurea herbicide, is a high-efficiency selective post-emergence stem and leaf treating agent, and can be used for preventing and killing 1-year-old broadleaf weeds in cereal crops. Is mainly absorbed and conducted by the leaf surfaces and root systems of the weeds. Typically, after application, sensitive weeds immediately stop growing and die after 1 week. Is suitable for preventing and killing weed such as Amaranthus retroflexus, herba Portulacae, flos Matricariae Chamomillae, herba Polygoni Hydropiperis, and fructus Chenopodii.
The long-term single use of the synergistic composition easily causes the drug resistance of weeds, pollutes the environment, and finds the synergistic composition which can improve the weeding effect and reduce the application dosage of active ingredients, thereby being the research and development key point of a plurality of pesticide companies in China. In the prior art, no report is provided about the compound use of trifluralin, acetochlor and thifensulfuron methyl.

The weeding composition provided by the invention is used for preventing and removing weeds in crop fields.
The crops are preferably cotton, rice, corn, soybean and the like. The weeds are annual weeds.
Compared with the prior art, the invention has the following beneficial effects:
the trifluralin, acetochlor and thifensulfuron methyl are compounded to have an obvious synergistic effect, so that the application dosage of active ingredients can be effectively reduced, the generation of drug resistance is slowed down, and the environmental pollution is reduced.
The trifluralin, acetochlor and thifensulfuron methyl are compounded to be used for preventing and removing crop weeds, and when the using dose is 50 ga.i./mu, the effect of preventing and removing the field weeds is about 90%.
Detailed Description
The invention will be better understood from the following examples. However, those skilled in the art will readily appreciate that the description of the embodiments is illustrative only and should not be taken as limiting the invention as described in detail in the claims
Example 1
10% of trifluralin, 40% of acetochlor, 2% of thifensulfuron methyl, 5% of sodium dodecyl benzene sulfonate, 3% of sodium methylene dinaphthalene sulfonate, 6% of NNO, 2% of sodium carboxymethyl starch, 2% of xanthan gum and the balance of attapulgite to 100%. The trifluralin-acetochlor water dispersible granule with the mass percentage of 52 percent is prepared by a conventional method.
Example 2
15% of trifluralin, 20% of acetochlor, 1% of thifensulfuron methyl, 4% of sodium lignosulfonate, 2% of sodium methylene dinaphthalenesulfonate, 2% of nekal, 3% of white carbon black and bentonite for 100%. The trifluralin-acetochlor wettable powder with the mass percentage of 36 percent is prepared by a conventional method.
Example 3: indoor determination of trifluralin, acetochlor and thifensulfuron methyl compounded purslane
The tested weeds: and (3) collecting mature seeds in the field of purslane seeds, and storing the seeds in a laboratory (regularly checking the germination rate every 1 month to be about 95%).
Reagent to be tested: trifluralin, acetochlor and thifensulfuron methyl; is commercially available.
The test method comprises the following steps: the soil for the test is special soil for the test collected from the land without medicine. Filling 3/4 parts of a flowerpot (the caliber is 9.5cm and the depth is 8cm) with test special soil; the flowerpot is placed in a pot containing water, and the water permeates from the bottom of the flowerpot, so that the soil is completely wetted. Sowing a certain amount of purslane seeds in a flowerpot, and covering soil for 1cm after sowing. And (3) carrying out soil spraying treatment by using a belt type crop sprayer according to the experimental design dosage 24 hours after sowing (the spraying pressure is 190kPa, the liquid spraying amount is 45L/mu, and the track speed is 1.48 km/h). The experiment was repeated 3 times. After the test material is treated, the test material is placed in a greenhouse to be managed according to a conventional method, the emergence of seedlings of the tested weeds and the reaction condition of the seedlings to the medicament are observed and recorded, the fresh weight of the overground part of each treated weed is weighed 30 days after the treatment, and the fresh weight inhibition percentage is calculated. The ED50 value of the drug was determined by DPS software, and the CTC value was calculated according to the Sun cloud Peel method.
And (4) analyzing results: as can be seen from Table 1, trifluralin, acetochlor and thifensulfuron methyl after compounding show synergistic and additive effects on purslane. Wherein the ratio of trifluralin to acetochlor to thifensulfuron methyl is 10:40:2, 30:20:0.5, 20:30:1 and 30:40:2, the synergistic effect is obvious when the ratio is 10:40:2, and the CTC value is more than 130. The ratio of trifluralin to acetochlor to thifensulfuron methyl is 5:10:1 and 1:1:1, and the additive effect is shown. Within the range of the tested mixture ratio, the ternary compound composition has no antagonism.
